One of Manard's earliest television appearances was a guest spot in a 1970 episode Mission: Impossible, during which time Leonard Nimoy was a regular player on that series. (Manard's episode, "The Amateur", also featured Peter Brocco and Anthony Zerbe.) Twenty five years later Manard's episode, Manard would appear in the 1995 Bonanza TV special, Under Attack, also featuring Nimoy. Manard was seen in at least four episodes of Bonanza between 1971 and 1972, including one with Don Keefer and another with Noble Willingham. He also appeared in a short film called Cowboysan with Ted Cassidy and directed by Susan Oliver.
